The functions of food processors mainly include, but are not limited to, making soy milk, squeezing juice, mincing meat, shaved ice, making coffee and / or preparing facial masks. When the existing meat grinder is working, the main machine drives the stirring blade assembly to rotate in one direction to cut the food, which causes the meat grinder to vibrate greatly and has a poor cutting effect on the food. Utility Model Content

[0003] The purpose of the present application is to provide a meat grinder which has little vibration during operation and has a good food cutting effect.

[0004] The present application provides a meat grinder.
